Water supplies are expected to be back to normal within three weeks

The source of an outbreak of the cryptosporidium bug in water supplies in Northamptonshire has been located.

Anglian Water said the bug was found in treatment works at Pitsford Reservoir.

The firm had advised 250,000 customers in the Northampton and Daventry area to boil tap water after the discovery of the bacteria in supplies on Wednesday.

A spokesman said half of the customers will be able to use tap water as normal by the end of next week, with the remainder back within three weeks.

Residents affected have all been urged to boil water for drinking and food preparation.

Schools which closed in the aftermath of the contamination have now reopened.

Ultra-violet light is being used at the treatment works to make the bug harmless.

This work is due to be completed over the weekend and once complete Anglian Water said it would be in a position to start getting newly treated water to customers.

Peter Simpson, chief operating officer of Anglian Water, said: "I'm pleased to report significant early progress, although our investigation into the root cause is ongoing.

"However, I'd like to stress the importance for all customers, in the affected area, of continuing to boil their water until further notice. I apologise for the inconvenience, but can assure everyone that we are working tirelessly to resolve this issue as quickly as possible."
